I have many stacks installed, my site uses Sitelok and Total CMS. Occasionally I see the following error which resolves itself and may be nothing at all to do with the issue?
Fatal error : Uncaught Error: Class ‘Michelf\Markdown’ not found in /private/var/folders/kt/mbl6kcsj307bq346wpk3v3w40000gn/T/com.realmacsoftware.rapidweaver8/RapidWeaver/37848/document-0x7fcca1998ea0/RWDocumentPagePreview/Teachers/andrew/index.php:130 Stack trace: #0 /private/var/folders/kt/mbl6kcsj307bq346wpk3v3w40000gn/T/com.realmacsoftware.rapidweaver8/RapidWeaver/37848/document-0x7fcca1998ea0/RWDocumentPagePreview/Teachers/andrew/index.php(141): totalpreview->format_text(‘
